Problems solved by technology
With the design method of the existing train wheels, the wheel rolling line value difference produces a large serpentine stress, and the index resistance of the train running is relatively large
[0003] In addition, the existing train wheels are used both as rolling wheels and as braking wheels. The high temperature generated during braking will make the wheels heated and softened. Therefore, excessive force should not be used when braking, and the braking time will be longer

The invention discloses a train wheel assembly with a shaft type differential mechanism. The train wheel assembly with the shaft type differential mechanism comprises a left half axle and a right half axle, a differential mechanism assembly, a wheel and a brake wheel, wherein the left half axle and the right half axle are symmetrically arranged and independent of each other; the differential mechanism assembly connects the left half axle with the right half axle; the wheel is mounted on the external ends of the left half axle and the right half axle; the brake wheel is mounted on the internal side of the wheel; the differential mechanism assembly comprises axle sleeves, external bushings and top plates which are symmetrically arranged on the left half axle and the right half axle; the axle sleeves are arranged on the left half axle and the right half axle in a sleeving manner; the external bushings are arranged outside the axle sleeves in a sleeving manner; flanges are arranged at one ends, close to each other, of the axle sleeves on the left half axle and the right half axle; flanges I are arranged at the two ends of the external bushings on the left half axle and the right half axle; the top plates are arranged on the external bushings through the flanges I in a spaced manner; the axle sleeves and the external bushings on the left half axle and the right half axle are connected with each other through bolts; key slots are correspondingly formed in the left half axle and the right half axle; through holes are formed in the axle sleeves in the same radial directions with the key slots; clamping keys are mounted in the key slots through the through holes in sequence; and marbles are arranged on one sides, facing towards the axle sleeves, of the clamping keys.
Description
technical field [0001] The invention relates to the technical field of train wheels, in particular to a train wheel assembly with a shaft type differential. Background technique [0002] Existing train wheel does not have differential gear, and in the place of train turning, the outward centrifugal force of curve is produced to car body, will overcome centrifugal force by the way of heightening outer rail. Because the two sets of wheel frames of a compartment of the train are a whole, the gauge at the curve is also different according to the curvature, and the gauge is widened differently. In the design mode of the existing train wheels, the wheel rolling line value difference produces a relatively large serpentine stress, and the indexing resistance of the train running is relatively large. [0003] In addition, the existing train wheels are used both as rolling wheels and as braking wheels, and the high temperature generated during braking will make the wheels heated and ...
